RHSA-2022:4592
Vulnerability from csaf_redhat - Published: 2022-05-18 01:20 - Updated: 2025-12-26 15:21An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",

RHSA-2022:4845
Vulnerability from csaf_redhat - Published: 2022-05-31 14:58 - Updated: 2025-12-26 15:21An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",

RHSA-2022:4896
Vulnerability from csaf_redhat - Published: 2022-06-03 13:51 - Updated: 2026-05-22 14:08An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

A flaw in the Linux kernel's implementation of RDMA communications manager listener code allowed an attacker with local access to setup a socket to listen on a high port allowing for a list element to be used after free. Given the ability to execute code, a local attacker could leverage this use-after-free to crash the system or possibly escalate privileges on the system.

A read-after-free memory flaw was found in the Linux kernel's garbage collection for Unix domain socket file handlers in the way users call close() and fget() simultaneously and can potentially trigger a race condition. This flaw allows a local user to crash the system or escalate their privileges on the system.

A flaw was found in OpenSSL. It is possible to trigger an infinite loop by crafting a certificate that has invalid elliptic curve parameters. Since certificate parsing happens before verification of the certificate signature, any process that parses an externally supplied certificate may be subject to a denial of service attack.

An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.

A flaw was found in rsyslog's reception TCP modules. This flaw allows an attacker to craft a malicious message leading to a heap-based buffer overflow. This issue allows the attacker to corrupt or access data stored in memory, leading to a denial of service in the rsyslog or possible remote code execution.

An out-of-bounds (OOB) memory access flaw was found in nft_fwd_dup_netdev_offload in net/netfilter/nf_dup_netdev.c in the netfilter subcomponent in the Linux kernel due to a heap out-of-bounds write problem. This flaw allows a local attacker with a user account on the system to gain access to out-of-bounds memory, leading to a system crash or a privilege escalation threat.

During processing of the parameters OpenSSL will call BN_mod_sqrt() with invalid arguments, causing the process to enter an infinite loop. The invalid EC parameters can be provided to OpenSSL through X.509 certificates (used in TLS connections), through public and private keys, through certificate signing requests and other places where applications process Elliptic Curve parameters.

If containers are in use, this requirement is not applicable.\nConfigure RHEL 8 to disable the use of user namespaces by adding the following line to a file in the \"/etc/sysctl.d/\" directory:\n\nuser.max_user_namespaces = 0\n\nThe system configuration files need to be reloaded for the changes to take effect. To reload the contents of the files, run the following command:\n\n$ sudo sysctl --system\n\n\nThe other mitigation for containers, if without disabling user namespaces, is blocking the pertinent syscalls in a seccomp policy file.

RHSA-2022:5439
Vulnerability from csaf_redhat - Published: 2022-07-01 00:52 - Updated: 2026-03-18 20:25An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

An arbitrary file write vulnerability was found in GNU gzip's zgrep utility. When zgrep is applied on the attacker's chosen file name (for example, a crafted file name), this can overwrite an attacker's content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.

When zgrep is applied on the attacker\u0027s chosen file name (for example, a crafted file name), this can overwrite an attacker\u0027s content to an arbitrary attacker-selected file. This flaw occurs due to insufficient validation when processing filenames with two or more newlines where selected content and the target file names are embedded in crafted multi-line file names. This flaw allows a remote, low privileged attacker to force zgrep to write arbitrary files on the system.",

RHSA-2022:7144
Vulnerability from csaf_redhat - Published: 2022-10-26 20:05 - Updated: 2026-05-14 22:32An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

There's a null pointer dereference and server-side request forgery flaw in httpd's mod_proxy module, when it is configured to be used as a forward proxy. A crafted packet could be sent on the adjacent network to the forward proxy that could cause a crash, or potentially SSRF via misdirected Unix Domain Socket requests. In the worst case, this could cause a denial of service or compromise to confidentiality of data.

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",

"text": "This is an important rather than a critical vulnerability due to its practical limitations. The flaw arises from unsafe left-shift operations in storeAtts() within libexpat, which, under extreme conditions (e.g., over 2\u003csup\u003e29\u003c/sup\u003e prefixed attributes), can lead to undefined behavior, memory mismanagement, and denial-of-service (DoS). However, exploitation requires specially crafted XML payloads several gigabytes in size (~6.5 GiB), which makes remote exploitation unlikely in real-world environments due to common upload limits and resource constraints. There is no evidence of arbitrary code execution, memory corruption leading to privilege escalation, or data leaks.",

RHSA-2022:7813
Vulnerability from csaf_redhat - Published: 2022-11-08 09:57 - Updated: 2025-12-26 15:21An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

RHSA-2022:8420
Vulnerability from csaf_redhat - Published: 2022-11-15 15:00 - Updated: 2025-12-26 15:23An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

RHSA-2023:0943
Vulnerability from csaf_redhat - Published: 2023-02-28 08:09 - Updated: 2025-12-26 15:29An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",

RHSA-2023:0975
Vulnerability from csaf_redhat - Published: 2023-02-28 08:14 - Updated: 2025-12-26 15:29An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",

RHSA-2023:0976
Vulnerability from csaf_redhat - Published: 2023-02-28 08:14 - Updated: 2025-12-26 15:29An out-of-bounds access flaw was found in zlib, which allows memory corruption when deflating (ex: when compressing) if the input has many distant matches. For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.

For some rare inputs with a large number of distant matches (crafted payloads), the buffer into which the compressed or deflated data is written can overwrite the distance symbol table which it overlays. This issue results in corrupted output due to invalid distances, which leads to out-of-bound access, corrupting the memory and potentially crashing the application.",

As rsync uses vulnerable zlib v1.2.8 package, which incorrectly handles memory when performing certain zlib compressing or deflating operations. This results in rsync to crash.\n\nNote - The issue wasn\u0027t publicly labelled as security vulnerability until 2022, but the fix was public since 2018.",
